PIPE-WRENCH.

SPEIFICATION formingpart of Letters Patent No. 668,467, dated February 19, 1901.

Application filed November 19, 1900. Serial No. 36,984. (No model.)

To all whom t may concern.'

Be it known that I, MOSES Z. VIAU, a citizen of the United States, and a resident of Malone, in the county of Franklin and State of New York, have invented a new and Improved PipeVVrench, of which the following is a full, clear, and exact description.

This invention relates to a pipe-wrench of that class in which a jaw is pivotally mounted on al hand-lever, the parts being arranged to engage the pipe in various positions of the jaw with respect to the lever.

The object of the invention is to simplify and strengthen the construction of these parts and at the same time to provide a wrench which may be engaged with the pipe in agreatnumber of different positions, and which also will automatically adapt itself to pipes of greatly-varying sizes.

rThis specification is a specific description of one form of the invention, while the claims are definitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a perspective view of the invention, showing it engaged with a pipe. Fig. 2 is a longitudinal section taken in the dat plane of the wrench.V Fig. 3 is a detail perspective view of the hardened jaw-face, and Fig. Il is a view showing the pipe in a second position.

a represents the handle of a wrench, the working end of which has a fork-like construction producing two arms a, such arms standing at an acute angle to each other and being serrated around both their inner and outer edges. The jaw or movable member, which is pivoted on the handle a just below the arms a', comprises two cheek-pieees b, rig'- idly connected together by a preferably integral web b'. (See Fig. 2.)

b2 represents the working face of the movable jaw, and this may, as shown in Fig. 3,

of a cheaper metal. The movable jaw has a transverse passage 7a3 formed therein, through which the jaw may be passed.

The web b is so arranged that it clears the ends of the arms a of the handle a, permitting the movable jaw to swing freely from one side of the handle to the other. This is also true of the working face b2 of the jaw. This construction enables me to place the working jaw in a great number of positions, in each of which it will be capable of gripping a pipe.

In using the wrench the pipe may be passed through the opening b3 of the movable jaw and made to assume either one of the four following positions namely, against the inner side of either one of the arms a' and against the outer side of either one of said arms. Further, the pipe may be engaged between the working face b2 of the movable jaw and the arms b at either of the two following positions: at the inner side edge of one of the arms a' (see Fig. 4) and at the outer side edge of the arm a', which is shown uppermost in Figs. 2 and Il. It will therefore be seen that the pipe may be taken in any one of six positions of the movable jaw without reversing the jaw. The jaw maybe reversed on the hand-lever, if desired, and, indeed, it may be used in various other ways which will suggest themselves to a skilled mechanic. It is also apparent that the wrench will automatically adjust itself to the size of the pipe. But one hand of the user is necessary to operate the wrench, since by passing the pipe through the opening b3 the pipe may be gripped by simply turning the wrenchto one side or the other. Also, owing to the shape of the working face of the movable jaw, the wrench may be readily engaged with a pipe which is laid flat against a wall or floor.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A pipe-wrench having a handle, one end of which is in the form of a fork, producing two arms thereat, and a movable jaw mounted on the handle intermediate the arms and having a transverse opening therein for the reception of a pipe.
